Cover photograph: Successful tests hare been carried out in Ontario. using a helicopter for delivering flexible hose to the scene of fire-fighting operations. The end of the hose is attached to a pump at the water supply source. The hose itself in connected 100 meter sections is paid out from the helicopter over the tree tops. and a water pressure of 40 to 45 kilograms is obtained at the outlet which is about equal to the pressure maintained in a hose laid out over the ground on rough terrain. The hauling-in of the air-borne hose is somewhat more difficult to perform, but this is more than compensated by the advantage of the quick laving-out of the line.
